Hello,
When I debug MPC574xP (MPC5743P), I find some module's memory are full of 'question marks' ????.
For example, the FlexRay module, according to Memmory Map, the address is 0xFFE50000-0xFFE53FF:
but in Trace32, it's full of ????, I can't read/write to the registers. (The other modules like MCU、Timer is running well)
How can I solve this issue?
Hi, in general '????' showing in the TRACE32 memory dump window means bus error.
If it is valid address range (do you have device part number with FlexRay?) then you should check MC_ME_PS3 register to check whether peripheral is active, potentially check CMPU, SMPU, XBAR and AIPS (PBRIDGE) peripherals where you can configure access rights.
